The spatial control of migrants on the Chihuahua border

EDGAR ABEL CASTRO (2023, [Artículo, Artículo])

This article tries to link the immigration policies of the United States and Mexico with the narrative developed by Michel Foucault. It shows how racism is the axis on which the State of biopower exercises its claims and its effects of power on bodies and on life. Thus, the current political rationality goes through the management of the living body of people, their health, and their spatiality. This principle extends to the homicidal function of the State. Two events that occurred on the Chihuahua border demonstrate this.

Structural analysis evaluationfor rollers of chassis dynoUsing finite element software

Jesús Emmanuel López Rizo ALFREDO CHAVEZ LUNA JAIME GONZALO SANTANA ESQUIVEL (2023, [Artículo])

This paper discusses the design considerations for a chassis dynamometer, focused on the rollers system used for measuring the power and torque of a vehicle in a university-level workshop. The design must prioritize factors such as safety, ease of use, adaptability to diverse types of vehicles, and the inclusion of safety systems to protect students and the vehicle. The work suggests adaptative features for the design, such as an adjustable fastening system and a compact and portable design, to adapt the structure into a university laboratory. The study also describes common methods for measuring engine power and torque using a chassis dynamometer, and the accurate and reliable measurement systems used for this purpose. This concludes with a discussion of the manufacturing methods used for the chassis dynamometer and a static analysis of the maximum effort capacity in each roller using Von Mises and Goodman fatigue theories. Developing a chassis dynamometer, in accordance the current patents available for workshop practices in a university is essential for providing students with comprehensive training.

Ecología ectoparasitaria del lenguado de California (Paralichthys californicus) y el lenguado diamante (Pleuronichthys guttulatus) en el Pacífico Norte de Baja California, México

Ectoparasite ecology of the California halibut (Paralichthys californicus) and the diamond turbot (Pleuronichthys guttulatus) in the North Pacific of Baja California, Mexico

Grecia Daniela del Carmen Esquivel Mondragón (2024, [Tesis de maestría])

El lenguado de California (Paralichthys californicus) ocupa el primer lugar según el índice de importancia de la comunidad (ICI) en el Estero Punta Banda (EPB), Baja California (México), y el segundo lugar en Bahía San Quintín (BSQ), mientras que el lenguado diamante (Pleuronichthys guttulatus) se ubica en tercer lugar de importancia en BSQ. Sin embargo, se conoce poco acerca de su parasitismo, lo que puede afectar su ecología. Se recolectaron 122 lenguados de P. californicus y 59 de P. guttulatus en EPB, BSQ y Laguna Manuela (LM), B.C., desde verano 2022 a primavera 2023, se identificaron once especies de ectoparásitos en ambos hospederos y se evaluó su prevalencia (p), abundancia (ap), intensidad (i) y frecuencia de ocurrencia (fo) por hospedero, localidades y estaciones del año (t), y las ap se correlacionaron con temperatura superficial del agua, surgencias, t y localidades. El lenguado de California, P. californicus, presentó diez especies de ectoparásitos y aquellas con mayores índices fueron Lepeophteirus sp. (p: 100%, ap: 16.5, i: 65, fo: 81.4%) en LM durante invierno 2023, Pontogeneia sp. (p: 50%, a: 2.3, i: 10, fo: 25.4%) en LM durante otoño 2022, y tanto Entobdella hippoglossi (p: 44.4%, a: 1.1, i: 6, fo: 15.3%) y Acanthochondria sp. (p: 22.2%, ap: 0.7, i: 5, fo: 6.8%) en LM durante invierno 2023. P. californicus mostró cambios significativos de ap contra las localidades, aunque sin cambios para t, y todas sus correlaciones (longitud total (lt), peso y ap versus t, surgencias, temperatura del agua y sitios) fueron significativas a excepción de ap contra t. Para el lenguado P. guttulatus se identificaron cinco especies de parásitos destacando con mayores índices al copépodo Lepeophteirus sp. (p: 100%, ap: 1, i: 1, fo: 19.1%) en EPB durante primavera 2023. Se presentaron diferencias significativas de ap con respecto al t, mientras que lt contra t, surgencias y temperatura del agua presentaron únicamente correlaciones positivas. Los parásitos de peces son importantes componentes naturales de sistemas ecológicos marinos, y debido a la sensibilidad de la relación huésped-parásito a cambios ambientales, su estudio permitiría generalizar respuestas en hospederos con el aumento o disminución de parásitos.

The California halibut (Paralichthys californicus) has the highest community importance index (ICI) in Estero Punta Banda (EPB), Baja California (Mexico), and the second highest in Bahia San Quintín (BSQ), and the diamond turbot (Pleuronichthys guttulatus) holds the third highest ICI in BSQ. A total of 122 individuals of P. californicus and 59 of P. guttulatus were collected in EPB, BSQ and Laguna Manuela (LM), B.C., from summer 2022 to spring 2023. However, very little is known about fish parasitism, which can affect host ecology in these sites. Eleven ectoparasite species were identified in both hosts and the parasite prevalence (p), abundance (pa), intensity (i), and frequency of occurrence (fo) were determined for each host, collection sites and seasons (t), the pa was related to water temperature, upwelling condition, t and sites. P. californicus presented ten species, and those with the highest indices were Lepeophteirus sp. (p: 100%, pa: 16.5, i: 65, fo: 81.4%) in LM during winter 2023, Pontogeneia sp. (p: 50%, a: 2.3, i: 10, fo: 25.4%) in LM during autumn 2022, and both Entobdella hippoglossi (p: 44.4%, pa: 1.1, i: 6, fo: 15.3%) and Acanthochondria sp. (p: 22.2%, pa: 0.7, i: 5, fo: 6.8%) in LM during winter 2023. The halibut P. californicus showed significance in pa regarding the sites, although with no change across t, and its correlations (total length (tl), mean weight, and pa versus t, upwellings, temperature and sites) showed significance, except for ap against t. Five parasites were identified in P. guttulatus, with the copepod Lepeophteirus sp. showing the highest indices (p: 100%, pa: 1, i: 1, fo: 19.1%) in EPB during spring 2023; the turbot P. guttulatus presented differences in pa regarding t, and its tl was correlated significantly with t, upwelling conditions and water temperature. Fish parasites are an important natural component of marine ecological systems and because the host-parasite relationship is sensitive to environmental changes, studying this relationship can allow for generalizing responses in hosts with an increased or decreased levels of parasites.
